Soil mixing

Soil mixing uses a wide range of techniques to inject binder agents to mix with the soil and form columns, for example, to reinforce the ground for subsequent construction. The type and amount of binder will determine the hydraulic and mechanic characteristics of the soil.

Soil mixing generally comprises three stages: premixing of the soil, injection of the binding agent and incorporation of the soil/binder mix. The technique produces no, or very little, spoil.

The structures produced by soil mixing can be columns, or also panels or continuous structures, such as trenches.
The technique works best with all types of loose soil, which is free of coarse elements.

Fields of application:

Improvement of compressible soils
Construction of cut-off walls
Construction of temporary ground support
Slope stabilization
